Relay Unit [RMT-6C or RMH-6C] Installation Instructions Relay Unit works together with Room Sensors and /or Tank Sensors to allow wireless connection to the boiler / wiring centre location. Support for up to 4 separate heating zones and 4 separate hot water zones. Must be paired with at least one Room Sensor and / or one Tank Sensor to operate. IN THE BOX: Relay Unit Backplate Safety Cover © 2 Save Energy Limited 2013 1 Introduction This Relay Unit is a part of the OWL Intuition range of cloud connected monitoring and control products. Its operation is dependant upon being paired to at least one Room Sensor and / or one Tank Sensor (supplied separately). The Relay Unit provides a remote, wirelessly connected relay that switches in concert with any paired Room Sensor and / or Tank Sensor. This allows for Room Sensors to be positioned for optimal temperature sensing (e.g. in the Lounge rather than in the Hall) without the requirement for wiring to that location. The Relay Unit is typically located immediately next to the boiler or wiring centre for ease of the wired connection and mains power supply. The Relay Unit relay will be switched whenever at least one of the paired devices is “calling for heat”. For safety, it will automatically switch off if it should stop receiving radio updates from the last remaining paired device calling for heat. It is recommended that this product is installed by a suitably qualified heating engineer, plumber or electrician. Please read the Safety Information section of this document before proceeding. 2 © 2 Save Energy Limited 2013 Version Information This Relay Unit is 230V mains powered with a changeover relay. It has 3 control buttons Comfort (+), Standby and Away with associated LED indicators. Device code RMT-6C is fitted with a digital temperature sensor.

It should be positioned away from draughts, direct heat and sunlight. The backplate is suitable for direct wall mounting using two wood screws No. 6 x 1” or M3.5 x 25mm into correctly sized wall plugs if required. Alternatively mount on to a single gang flush wiring box complying with BS4662, using two M3.5 screws. 1. Ensure there will be enough space to allow easy screwdriver access to the two captive screws located at the base of the backplate. 2. Electrical Connections: - If in any doubt whatsoever, do not continue, but consult a qualified electrician or heating engineer. WARNING: ISOLATE THE MAINS SUPPLY BEFORE COMMENCING INSTALLATION For existing wireless installations, remove the old relay box to expose the wiring back to the boiler / wiring centre. Check the wiring at both ends to correctly identify which wire is Live, Neutral, Switched Live and any Earth connections. For new installations, run a new cable between the boiler and chosen Relay Unit Location. The recommended cable size is 1.0mm2. See diagram below. a. Ensure that the Live feed to the Relay Unit is correctly fused (3A or 5A maximum) - This protection is normally provided by way of a fused spur © 2 Save Energy Limited 2013 5 powering the heating system. b. Fix the backplate - Offer the backplate supplied to the wall in the position where the Relay Unit is to be mounted (with the cable through the central aperture of the backplate) and mark the fixing positions through the slots in the backplate. Drill and plug the wall, then secure the plate into position. The slots in the backplate will compensate for minor misalignment of the fixings.
